Schlumberger said Sept. 9 that it has released its SenTurian subsea landing string electrohydraulic operating system. Technological advances have resulted in an innovative, shorter modular system, which allows safe, reliable and efficient completion installation, well cleanup and well testing from a dynamically positioned vessel in water depths to 15,000 feet.

SenTurian is the world’s first and only in-riser system designed and certified in accordance with the International Electrotechnical Commission’s IEC 61508 SIL 2 reliability specifications for safety-related systems. IED is the international standards and conformity assessment body for all fields of technology. In addition, the design enables compliance with ISO 13628-7 standards by providing electronic redundancy and pressure readout for each subsea function.
